Which of the following is combined with an inductor to make a resonant circuit?

A resonant circuit, often called a tuned circuit or an LC circuit, is created by combining an inductor (L) and a capacitor (C). In this circuit, electrical energy oscillates back and forth between the magnetic field of the inductor and the electric field of the capacitor. This specific combination allows the circuit to resonate at a precise frequency, making it essential in radios for tuning into a desired signal while rejecting others. Components like resistors dissipate energy rather than storing it, and diodes control the direction of current flow, so neither creates resonance when paired with an inductor.
